Texans for Natural Gas uses misleading data on methane in Texas

Recently, Texans for Natural Gas (TXNG) issued a report claiming methane emissions have drastically decreased in several of the largest natural gas producing counties in Texas from 2011 to 2016.

The notion of methane emissions rapidly declining across Texas during the largest U.S. oil and gas boom of the century is described in the report’s blog post as amazing, which in fact it would be if the report were accurate. It isn’t. The TXNG report doesn’t even come close to providing a complete representation of methane emissions across the featured Texas counties. TXNG claims methane emissions declined 51 percent in several of the state’s largest producing natural gas counties, and 39 percent across ten of the largest oil-producing counties.

And here’s what data is missing: methane emissions generated from onshore production and gathering. Simply put, the vast majority of emissions aren’t even included. (What’s even worse, their original report failed to disclose that the emission data referenced in TXNG’s blog post only accounted for methane emissions from large midstream  gas facilities.) The revised report’s claims about 2016 reductions in Midland County only account for emissions from six processing plants and compressor stations while ignoring the over 2,000 oil and gas wells. Drawing broad conclusions from a tiny fraction of facilities is shoddy analysis at best and deliberately misleading at worst.

Texas cities, businesses, and schools know the economic upside of clean energy

The City of Georgetown, Texas committed to 100% renewables.

Recently, the message on Texas clean energy has been getting clearer – the market is driving the clean energy economy forward. And some of those spreading the message are making it loud and clear.

Case in point, the city of Georgetown, a predominately Republican city, shifted to 100 percent renewable energy in 2015. Jim Briggs, the city’s General Manager-Utilities, clarified, “We didn’t do this to save the world – we did this to get a competitive rate and reduce the risk for our consumers.” Additionally, Briggs notes that switching to renewables will hedge against future fuel and regulatory risks.

Even if reducing risk was the primary reason for Georgetown going 100 percent renewable, the move will also slash air pollution and contribute to a healthier Texas. This shift not only has brought about a significant price decline in electricity, but has also brought millions of dollars of new investment to the city – proving to be a great economic development tool.

And Georgetown isn’t the only example. More and more Texas voices – ranging from multimillion dollar corporations to universities and school districts – are speaking up about their investments in clean energy. And the motivating reason is the same: economics. Read More »

Rooftop solar and EVs save water and cut pollution – and data can help us go further

Thanks to improvements in technology, it’s easier than ever to be green.

Solar panels and electric vehicles (EVs) are two prime examples of technologies that can help people minimize their environmental footprint, without sacrificing comfort or having to radically change their daily behavior. But the question still remains: How much of an environmental benefit do these technologies actually produce? And, are there actions that owners of these technologies can take to minimize their pollution footprint even more?

A new paper by my colleagues and me, recently published in Energy Economics, attempts to answer these two questions for households in Austin, Texas. These homes are part of Pecan Street Inc., a living smart-grid laboratory with the largest customer energy-use database on the planet. Using detailed household-level data from 2013-2015, we were able to track solar panel performance and EV use and charging patterns, and match these actions to two important environmental impacts: water use and greenhouse gas (GHG) emissions.

Our paper confirms that, in Texas, residential solar panels uses less water and pollutes the air less than using the central-grid power (based on its electricity sources during those years), and driving an EV instead of a gasoline vehicle generally reduces the household’s water and emission footprint, even though EVs charge from the grid. Moreover, our analysis demonstrates how carefully examining energy-use data can help us make sure we’re maximizing clean energy’s benefits. Read More »

3 things my climate-skeptic dad taught me about clean energy advocacy

Kate Zerrenner and her dad.

As an advocate for the air, water, and economic benefits that clean energy provides, I find some of my most challenging – and maybe most rewarding – work is trying to engage climate-skeptic lawmakers at the Texas Capitol in Austin.

To facilitate that work, I use lessons I’ve learned from my dad, who lives in San Antonio and with whom I don’t often agree when it comes to our approach on the environment. In the spirit of the holidays, I want to thank him for all those conversations in which we didn’t see eye to eye. Little did I know then, he was teaching me the tools of my trade.

Here are three lessons my dad taught me that I use daily in my work as a clean energy advocate. Read More »

New Texas Permian oil and gas flaring report reveals excessive gas waste and major gaps in operator flaring practices

As companies flock to West Texas’ Permian Basin to cheaply drill for and extract oil and gas, some operators are flooding the night sky with natural gas flares, polluting the air with unhealthy and climate-altering pollutants, and wasting copious amounts of this important, domestic energy resource.

The Permian Basin, which stretches across 75,000 square miles in West Texas and southeastern New Mexico, is in the midst of one of the largest energy booms of the century. An estimated 60-70 billion barrels of recoverable oil is located in the area, which is worth roughly $3.3 trillion at current prices, according to IHS Markit. Oil isn’t the only resource in abundant supply. EIA estimates that operators in the Permian are producing 7.3 billion cubic feet of natural gas per day. But a rush to produce higher value oil has some Permian drillers simply flaring the gas instead of investing in gathering and pipeline infrastructure.

A new EDF flaring report, released this week, has uncovered a wide discrepancy between flaring rates among the top 15 oil and gas producers working in the Texas Permian Basin. Some of the oil and gas producers studied in the report are wasting close to 10 percent of their produced gas due to flaring practices, highlighting the fact that the oil and gas industry continues to struggle to control natural gas waste.

How clean energy just overtook coal in this competitive electricity market

Look around the U.S. and you’ll find plenty of examples of smart policy that is driving the adoption of cleaner, more efficient energy resources. In particular, California, New York, and Illinois are all leveraging policy to reduce carbon pollution and transition to a 21st century electric grid.

But in addition to those success stories, markets also are achieving significant clean energy results – and nowhere is that more evident than here in Texas.

In 2001, the Lone Star State transitioned to a competitive electricity market that (for the most part) puts the cheapest energy resources on the grid first. Since then, wind has grown from supplying less than 1 percent of the state’s electricity to over 20 percent for the first half of 2017. And as cheap natural gas remains plentiful and renewable costs keep falling, expensive coal is getting pushed out of Texas’ market. In fact, wind power capacity just overtook coal capacity.
